Oxalis recommendations?

Dear Friends,
Many thanks for all the recommendations. I will have to study
these more. I've checked out some pix on the wiki.
Both Oxalis gracilis and Oxalis inaequalis sound kinda like
'my kind of flower' although O purpurea sounds easy and with a wide
range of variety. Guess I'll have to keep my eyes open for BX
offerings.
O. versicolor is just covered in blooms now. My only
deliberate species.
Thanks for all the input. Best Jim W.
